States The present invention generally relates to window structures and more particularly to such windows that are provided in buildings in which a sash member is mounted within a frame that is sealed in a wall opening in such a manner that the sash member may be fixed in a closed position or moved to an open position by tilting or hinging the sash member with the further feature that the sash member may be removable for cleaning purposes or for replacement of the window panes. A

One example of such an installation is in churches or other similar buildings in which the windows may be opened for ventilation purposes but which are left closed for relatively long periods of time with there being no person in attendance in the building thereby requiring that the window be absolutely weatherproof. Therefore, it is the primary object of the present invention to provide such a window in which the sash member is hingedly connected or mounted on the frame in a manner which enables easy removal of the sash member from the interior of the building but yet which maintains the sash member in completely sealed relationship to the frame member when installed and when in closed position.

Yet another important object of the present invention is to provide a window construction of the type in which the sash member is hingedly and detachably mounted which is extremely simple in construction, easy to remove and replace, easy to install, effectively sealed and otherwise well adapted for mass production by using aluminum extrusions for the frame and sash member.

Another object of the present invention is to provide.

a window construction in accordance with the preceding objects in which there is a novel structural arrangement for hingedly mounting the sash member on the frame which enables a relatively large surface contact for the hinge which provides for a more stable hinge construction and one which is more easily operated and is long lasting and dependable.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Referring now specifically to the drawings, the numeral 10 generally designates the entire window assembly which includes a frame generally designated by the numeral 12 and a sash generally designated by the numeral 14.

The sash member 14 includes a pair of peripheral members 16 and 18 which are each provided with an inwardly extending flange 20 and 22 at the inner edges thereof in which the flanges 20 and 22 are spaced from each other and rigidly connected by a web 24. This construction defines an annular groove 26 in the outer periphery of the sash member and the corners of the framework defined by the peripheral members 16 and 18 as well as the flanges 20 and 22 in the web 24 are mitered and connected by angle connectors 28 which extend around the corner within the groove 26 and are secured to the webs 24 by fasteners 30 thereby forming a rigid framework for the sash with the flanges 20 and 22 forming a peripheral inwardly extending surface.

Disposed against the flange 20 is a glass panel or pane 32 and disposed against the flange 22 is a glass pane or panel 34. The glass panels 32 and 34 are retained in sealed relation by metal putty 36 or the like and also the usual fasteners employed in maintaining glass panes in a metal sash whereby the glass panes 32 and 34 will be securely held in position and sealed to the peripheral members 16 and 18 by the putty 36, thereby forming a rigid unit of double pane construction.

The outer surface of the sides of the sash member 14 are each provided with a plate 38 which is mounted against the outer surface of the flange members 16 and 18 and secured in position by a suitable fastener member 46 although the plate 38 may be formed integral with the flanges 18 and 16 or secured thereto in any suitable manner. The plate 38 is disposed closer to the top of the sash than to the bottom and the downwardly facing edge of the plate 40 is provided with a semi-circular recess 42 which forms a bearing surface for engagement with a portion of the frame as designated hereinafter. The construction and configuration of the semi-circular surface 42 is shown clearly in FIGURE 5 and the relationship thereof to the frame is shown in FIGURE 2.

The flange member 16 is provided with a peripheral laterally andoutwardly extending sealing flange 44 which extends across the bottom of the sash member 14 and up the side edges thereof to a point generally coincident with the upper extremity of the semi-circular bearing recess 42. The upper terminal edges of the flange 44 are inclined as designated by the numeral 46.

The flange 18 is provided with a laterally and outwardly extending flange or lip 48 which extends across the top and down the side edges thereof to a point below the top extremity of the semi-circular recess 42 and this orientation of structure is also clearly shown in FIG- URE 5.

The frame 12 is set into a building opening in any suitable manner and is snugly and sealingly retained in such a building opening. i

The frame 12 includes a top frame member 56 and a.

bottom frame member 52 and side frame members 54 and 56. The frame members have mitered corners and are interconnected by a right angle connector 58 secured in place by fasteners 66. Each side member 54 and 56 is provided with a plate 62 mounted thereon with the plate 62 carrying a cylindrical inwardly extending projection 64 secured thereto by a fastening member 66 although the cylindrical projection 64 may be integral with the plate 62. The outer end of the cylindrical projection 64 is provided with segmental recesses 68 as shown in FIG- URE 3 which recesses receive an inwardly extending flange 70 on one side and an inwardly extending flange 72 on the other side. The flange 72 is carried by a laterally extending flange 74 that has a recess 76 therein for receiving the flange 44 on the sash 14. The other flange 79 is carried by a laterally extending flange 78 which extends beyond the extremitiesof the sash and is providedwith a groove 80 receiving the edge of the flange 18 thus sealing the flange 18 to the flange 78. t I The previously mentioned structure is that which appears below the cylindrical member 64. Above the'cylindrical member 64, the structure is just reverse to that shown in FIGURE 3; a In other words, the upper portions of the side members 54 and 56 which face the lip 48 are provided with the flange 74 and rib or flange 72 together with-the pocket 76v for receiving the lip r flange 48 while the outer surface of the upper portion of the frame is provided with the inwardly extending flange 78 having the groove 80 therein which in this case will receive the top edge portion of the flange 16, that is, that portion above that portion of the flange 16 having the lip 44 thereon.

As clearly illustrated in FIGURE 4, the lower edge of the flange 80 and the associated flange 70 is inclined as illustrated by the numeral 82 for engagement by the inclined surface 46 on the lip or flange 44.

In FIGURE 1, it is noted that the lower ends of the flange or lip 48 is spaced from the corresponding flange 78 a suflicient distance that it will enable the sash 14 to 'be swung inwardly about the top edge thereof to the 4 principles of the invention. Further, since numerous modifications and changes will'readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A ventilated window comprising a Window frame adapted to be secured in a wall window opening, a window sash comprising a sash frame, aligned pivot means formed on opposite sides of said window frame and sash frame for pivotally supporting the sash for swinging movement of the sash in relation .to the window frame, pane forming seat means on said sash frame, said pivot means comprising a cylindrical projection carried by oneof said frames at each side thereof, and a plate having a downwardly facing semi-cylindrical lower end forming a beardotted line position illustrated in FIGURE 2. When this occurs, the flange or lip 44 becomes aligned with a notch or groove 84 in the top inner portion of the flange 74 7 thus permitting the sash member to merely be lifted out of the frame member by moving the sash member in the angulated plane in the direction of the arrow as shown in FIGURE 2 and, of course, for reassembling the sash member, this procedure is reversed.

Any suitable lateh mechanism may be provided at the top of thesash or at the bottom thereof for latching the top or bottomof the sash tothe frame thus retaining the sash'in closed position. Such a latch should exert closing force on the sash so that the peripheral sealing engagement between the flange 44 and the seat or recess 76 and between the flange 16 and the groove 80 is effected throughout the periphery with the corresponding engage ment' being provided on the inner surface of the window.

Thus, with the present invention, a double seal is provided throughout the area of the window except for that small portion at the hinge area. However, the hinge itself acts as a double seal since the semi-circular recess 42 has surface engagement with the top portion of the cylindrical projection 64 and the flange 72 is sealingly engaged with the flanges 70 and '72 thereby providing a further'sealfor the omitted area of the flanges 73 and log surface for the projection on the other of said frames thereby removably and pivotally connecting the frames, said frames having inwardly, extending and overlapping sealed flanges at the inner and outer surfaces thereof for providing a double seal for the sash frame, said cyhndrical projection being provided on the interior surface of the window frame, said plates beingon the outer surface of the sash frame and extending over substantially one half of the area of the projection for providing a vertical component of weather seal, the inner surface of the up per portion of the sash being provided with an outwardly extending flange, the outer surface of the lower portion of the sash having an outwardly projecting flange, the upper inner portion of the window frame having a rabbeted shoulder therein for receiving the flange on the inner surface of the sash frame, the outer lower portion of the window frame having a rabbeted shoulder for receiving the flange on the outer surface of the lower portion of the sash frame, theshoulders on the upper outer portion of the window frame having inclined grooves 48 disposed to the interior of the building structure therea therein disposed in angular relation for permitting sliding movement of the flanges on the inner surfaces of the sash frame during removal of and insertion of the sash frame in relation to the window frame when the sash frame is inclined to an open position.

' 2. The combination of claim 1 wherein the lower inner periphery of the window frame is provided with a laterally inwardly extending flange having a groove therein for receiving the edge of the lower inner portion of the sash frame when in closed position, the upper outer portion of the window frame having a laterally inwardly extending flange having a groove therein receiving the outer edge of the sash frame when in closed position thereby providing substantially two peripheral weather seals between the sash frame and the window frame.
